Hello,
while running SFLOW:2nd order stokes waves on flat bed,i stuck with an issue 'hypre solver broke down'.

REEF3D::SFLOW

HYPRE solver broke down! Emergency Stop! 1

--------------------------------------------------------------------------
mpirun has exited due to process rank 0 with PID 0 on
node DESKTOP-VHTQJFA exiting improperly. There are three reasons this could occur:

1. this process did not call "init" before exiting, but others in
the job did. This can cause a job to hang indefinitely while it waits
for all processes to call "init". By rule, if one process calls "init",
then ALL processes must call "init" prior to termination.

2. this process called "init", but exited without calling "finalize".
By rule, all processes that call "init" MUST call "finalize" prior to
exiting or it will be considered an "abnormal termination"

3. this process called "MPI_Abort" or "orte_abort" and the mca parameter
orte_create_session_dirs is set to false. In this case, the run-time cannot
detect that the abort call was an abnormal termination. Hence, the only
error message you will receive is this one.

This may have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).

You can avoid this message by specifying -quiet on the mpirun command line.

thanks in advance.

I have same error when used hypre v2.28 or v2.29. The error is solved with hypre v2.27.

I have heard that this is an issue on Windows with the Linux subsystem. Are you using this one as well?

[hridu]

yes im using windows 10 with Ubuntu subsystem.

Best to use hypre v2.27 then for now. Not sure that there anything we can do at the moment.
